With a lifting capacity of 3,600 [5] to 4,000 tons, [6] a total boom length of 144 meters [3] and a total gross weight of 5,350 tons. [3] The XGC88000 crawler crane became the largest tracked mobile crane in the world, [ 7 ] [ 8 ] [ 9 ] beating out the previous record holder, the Liebherr LR 13000 when it officially came into production in 2013.
Generally, these cranes are able to travel on highways, eliminating the need for special equipment to transport the crane unless weight or other size constrictions are in place such as local laws. If this is the case, most larger cranes are equipped with either special trailers to help spread the load over more axles or are able to disassemble ...
In 1959 crane expert R.H.Neal, hydraulics specialist F.Taylor, and design director Bob Lester, integrated all three and modernized cranes. The Coles Hydra Speedcrane appeared in 1962, further modified with the 10-ton fully telescopic hydraulic boom in 1966, followed in 1968 by the 30-ton "Husky" military versions with four-wheel drive .
Some new cranes have a 120-tonne load capacity, enabling them to lift up to four 20-foot (6.1 m) or two 40-foot (12 m) containers. Cranes capable of lifting six 20-foot containers have also been designed. Post-Panamax cranes weigh approximately 800–900 tonnes, while the newer-generation super-post-Panamax cranes can weigh 1,600–2,000 tonnes.
They also have a small footprint compared to gantry or Goliath cranes. The performance of super-heavy jib cranes is measured in tonne-metres, the product of weight and lifting radius, typically as much as 100,000 tonne-metres for large cranes. [8] Sarens offer a range of such cranes from 90,000 to 250,000 tonne-metres.

An overhead crane, commonly called a bridge crane, is a type of crane found in industrial environments. An overhead crane consists of two parallel rails seated on longitudinal I-beams attached to opposite steel columns by means of brackets. The traveling bridge spans the gap. A hoist, the lifting component of a crane, travels along the bridge.
Ship-to-shore gantry cranes are imposing, multi-story structures prominent at most container terminals, used to load intermodal containers on and off container ships. They operate along two rails (waterside and landside designations) spaced based on the size of crane to be used. Ship-to-shore crane elements. Lateral movement system:
